Since March 1, we have had 5-9 feet of snow and 5-9 inches of snow water equivalent (SWE) throughout the Central Wasatch. This has been a great test of our buried persistent weak layers (PWL). Prior to the start of this stormy March we had a layer of very heavy snow (almost rain) that fell with an associated dirt layer on March 2. This melt-freeze layer was buried and in turn faceted, causing a seven-to-ten day avalanche cycle. Recently, we have had extended column tests showing that while the layer is still reactive, it is becoming harder to initiate propagation. The last avalanches …
